NOTES
During the creation of cataract incisions, you should see bubbles start at the posterior portion of
the incision and move anteriorly through the cornea to the sterile buffered saline solution in the
suction ring. If creating posterior penetrating incisions in the cornea, watch for bubbles in the
aqueous humor that rise to the apex of the anterior chamber. Then monitor bubbles through the
cornea. Small bubbles appear as the laser penetrates the anterior cornea with overcut into the
sterile buffered saline solution.
During the creation of arcuate incisions, you should not see bubbles in the aqueous humor. If
bubbles are seen penetrating the posterior cornea, abort the treatment, and release the patient.
Laser treatment can be paused at any time by pressing the PAUSE TREATMENT button on the
control panel or by releasing the laser footswitch. When laser treatment is paused, a “Clearable
Error” message displays, and you must press the OK button to acknowledge and clear the error.
To resume laser treatment, release the laser footswitch and then press it again.
Refer to the following page for guidance on how to proceed when treatment is interrupted.
QUICK TIP: TREATMENT
Press firmly on the footswitch and do not lift, especially during the capsulotomy. If there is any
interruption during the capsulotomy, you may not restart the capsulotomy but may continue to
lens fragmentation, arcuate incisions, and then to the cataract incisions, if planned. If there is
any pause during the fragmentation, arcuate, or cataract incisions, you can resume the
treatment. If you have a suction loss during laser treatment, you may not continue with
treatment.
